Margaret, your German English comparison on class matters reminded me of the Ford Motor manufacturers back in the 70s. It was owned by a German company then, and there was a great deal of industrial unrest in the English one, and very little in the German one, which had similar pay and conditions. The execs came over to the English branch to see what was going wrong.
They concluded that the problem in the English one, was that the executives lived in a different area from the workers, spoke a different version of English and sent their children to different schools, and this was the basis and cause of the deep mistrust leading to industrial unrest.
This was a classic case of class divisions causing unnecessary problems.
Johanna Karl Marx had no time for lazy people who did not work. He lumped the idle rich and the idle poor together in his condemnation! (Of course, not all rich are idle, and not all poor are idle by any means, but some are)
